Specification forming part of Letters Patent No. l59,070, dated January 26, 1875; application filed July 11, 1874.

To all wliom it may concern Be it known that I, HENRY G. BULL, of New York, in the conntyof New York and State of New York, have invented a new and useful Improvement in' the Construction of Street-Oar Truck-Frames, of which the follow-- ing is a specification:

The invention consists in connecting the sections of the tubular truck-frame by tubular joints, thus forming a continuous passage therein, as and for the purpose hereinafter described.

In the accompanying drawing, Figure 1 represents a plan view of a truck-frame constructed-accordingtomy invention. Fig. 2 is an edge view, showing the'pedestal-blocks. Fig.

3 is an end elevation.

Similar letters of reference indicate corresponding parts; i 7 isthe truck-framep. B B, the axles; O

wheels. This frame A is made of tubing the parts being connected together by means of screws and corner-pieces D, in the usual manner, having one or more longitudinal tubes, E, connected to the ends of the frame by the pieces G represents the pedestal- Thus constructed, the entire frame is adapted for use as a water-tank for supplying the boiler, and may beof any size foundnecessary or practicable. ,The connections of feed and discharge pipes may be made in the usual or welhknown man- I do not claim a vehicle-frame made of tubes or tubular sections; but 7 7 Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

The car-truck frame formed of tubular sections and tubular connecting corner-pieces D, combined as and for thepnrpose set forth.
